Problems solved by technology
[0008] In the process of implementing the present invention, the inventors found that LTE networks may also face paging signaling storms, and manual optimization of paging parameters involves time-consuming and labor-intensive tasks. The existing Self-Organized Network (SON) technology also Self-optimization of paging parameters is not supported, resulting in low paging performance of the LTE network and high cost of manual network optimization, so it is necessary to increase the paging self-optimization function

The embodiment of the present invention discloses a method and system for self-optimizing paging parameters in a long-term evolution network, wherein the method includes: eNB monitors and counts paging load and paging performance; eNB triggers paging according to a preset period or based on a preset event , report the statistical results of the paging load and paging performance obtained by statistics to the OAM system; the OAM system determines whether to modify the paging parameters and the paging parameters that need to be adjusted according to the statistical results of the paging load and paging performance; if necessary To modify the paging parameter, the OAM system uses a preset optimization algorithm to calculate the adjustment value of the paging parameter that needs to be adjusted, and sends a paging parameter adjustment notification message to the eNB; the eNB adjusts the paging parameter according to the paging parameter adjustment notification message. The parameter is adjusted, and the user terminal UE is notified of the adjusted paging parameter. The embodiment of the present invention can realize self-optimization of paging parameters in an LTE network, effectively improve network paging performance, and reduce manual network optimization costs.
Description
technical field [0001] The invention relates to communication technology, in particular to a method and system for self-optimizing paging parameters in a long-term evolution network. Background technique [0002] Long Term Evolution (LTE) is a new generation of wireless communication system launched by the 3rd Generation Partnership Project (3GPP). It is an evolution technology of the third generation (3G), generally referred to as 3.9G or Quasi 4G. There are currently three versions of LTE, R8, R9, and R10. Among them, the R8 and R9 versions were frozen at the end of 2008 and 2009 respectively. The R10 version representing 4G technology is also called the advanced long-term evolution technology (LTE-Advanced). The standardization work was completed in September. LTE adopts Orthogonal Frequency Division Multiplexing (OFDM) and Multiple-Input Multiple-Output (MIMO) technology as the mainstream standard for its wireless network evolution. LTE R8 version can provide 100Mbit / ...
